once cooking enabled the gut to become smaller,then the energy spared from looking after the gut was made available to the brain a very expensive organ that certainly needs to be fuelled from somewhere.
So it seems likely that what cooking did was make those big brains possible.But the big brain which has served us so well is now causing us great problems in the 21st century.
We are left programmed to eat energy-rich, sweet, fatty foods.
The experiment shows that over millennia, we have evolved a battery of antennae to further our quest for fatty food. We in the modern world have used our hungry brains
to create an environment in which we can we eat what we want,
where we want,and when we want.
Here we are in the 21st century the foods that come out of our supermarkets are always, every year, more energy-rich than before.
We're constantly exposed to foods that give us tremendous amounts of energy and we can't resist them. That big, hungry brain, that's done so much to make us who we are is in danger of destroying us.
Modern humans have come a long way since our ancestors survived on a diet of raw fruit and vegetables.Our food has helped us
overcome the disadvantage of being relatively puny.But maybe it's the discovery of cooking which has equipped us with brains big enough to take over the planet.
